Blank Screen!

Hello folk! I am new to roll20, and when I tried to launch a campaing everything on the map was blank. I was about to start the tutorial, but I failed due to the problem that nothing appeared on my screen. I tried all option to draw, nothing happened. I could choose manipulating options, but nothing appeared.  Others (my friends) joined the game, and they told me that all I did was there (random lines and stuff all over the screen). We couldn't find out why is this happening. (I am using Chrome.)

Greetings Istvan,&nbsp; Please carefully work through to the first three steps of our guide to Solving Technical Issues (. <a href="https://roll20.zendesk.com/hc/en-us/articles/360037255194-Solving-Technical-Issues" rel="nofollow">https://roll20.zendesk.com/hc/en-us/articles/360037255194-Solving-Technical-Issues</a> ): Step 1: Make sure to use the right browser, Please check if these issues persist when using both Chrome and Firefox.
